Rcsults are presented of a re-examination of the holotype of Xanthidium penicillatum, a species of dinoflagellate cyst first reported by Ehrenberg (1843) from the Corallian of Poland and validly published by him in 1854. It is shown to correspond exactly in morphology with Systematophora fascicutigera (Klement, 1960), from the Upper Jurassic of Germany. The new combination Systematophora penicillata (Ehrenberg, 1854) is proposed and S. fasciculigera is rejected as a subjective junior synonym.

Key words: Dinoflagellata, taxonomy, Upper Jurassic, Poland.
